Hole pile excavation safety protection device

Abstract

The invention discloses a hole pile excavation safety protection device. Four supporting columns A (6) are fixedly mounted on the upper portion of a base (5). A top seat (9) is fixedly mounted on theupper portions of the four supporting columns A (6) and is fixedly connected with the lower portion of a framework (10). Protection nets A (2) are mounted on the two side faces of the framework (10),and a protection net C (13) is mounted on the rear portion of the framework (10). The lower portion of the rear end of the framework (10) is hinged to the rear end of a protection cover (1). The protection cover (1) covers a buffer (14) in a manner of inclining a front end cover, wherein the buffer (14) is mounted on the upper portion of the front end of the framework (10). The lower ends of two splayed steel wire ropes (11) penetrate through the four corners of the framework (10) to be clamped by steel wire clamps and then are placed in the four supporting columns A (6). The upper ends of thetwo splayed steel wire ropes (11) are connected with lifting rings (12). According to the hole pile excavation safety protection device, the situation that in the hole pile excavation process, hole walls collapse, hole opening objects and lifting objects fall off by accident, and construction personnel at hole bottoms are hurt can be avoided, and meanwhile the excavation size and the inclinationdegree in the hole pile excavation process are controlled.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a safety protection device for hole pile excavation. Background technique [0002] In engineering construction, structures and structures such as highways, bridges, houses, and geological disaster prevention and control are often affected by various factors such as the thickness of the surface soil covering layer and complex terrain conditions, and the foundation form is often designed as a pile foundation. However, in the construction of pile foundations, due to the influence of environmental protection and limited use of machinery, only manual excavation can be used for hole-forming construction of hole piles. The construction of artificial excavated piles is to determine the hole position and size of the hole piles, and then excavate step by step from the ground down according to the geological conditions and graded excavation depths (sometimes without retaini...

AI Technical Summary

Problems solved by technology

During construction, muck falls, buckets fall out of control, hole walls collapse, and other objects fall outside the hole, etc. Any falling phenomenon can cause injury or death to the construction personnel in the hole.

In addition, during the excavation of hole piles, due to the high safety risk, the quality inspectors cannot carry out process inspection on the hole quality of hole piles. The hole piles need to be re-trimmed, which not only affects the construction period, but also increases the loss of rework and repair
